5 stars doesn't even begin cover how wonderful Carmie and Katie are! We started our 20 month old with Bright Horizons with him saying at best, one or two words. Less than a year later he is speaking at a level compatible with his peers! Katie truly unlocked his voice and we are forever grateful! She is so kind and welcoming, our son was beyond excited to see her every week! If you are even slightly concerned with your baby's speech, look no further!
